The study of the fluid behavior in the sewage system of building systems is highly complex and difficult to predict. This is due to the characteristics of the problem, such as free surface runoff, high randomness in system flow rates and inhomogeneity characteristics of the liquid containing faeces, paper, food remnants, soap and others. Even though it is one of the major responsible for the large amount of post-work technical assistance in Brazil, this topic is not much studied. Therefore, this paper analyzes the influence of design variables on runoff behavior within sewage systems. For this purpose, experimental tests were performed in a residential building, and the analysis parameters were: the height at which the discharge is performed, the flow / volume of the discharges, the types of connections used in the plumb diversion and the sub-collector configurations. Thus, with the results of this research, it is possible to help in the understanding of decision making contributing to a better performance of buildings. As a result it can be observed that the higher the discharge height, the lower the transport speed of the media and the lower the height of the water slide within the network, thus the greater the chance of solids retention within it. In relation to the discharge flow, the higher the flow values the higher the transport speeds of the media. Connections installed on the network, both in the plumb diversion and the sub-manifold, have a considerable influence on media transport speeds and should be chosen to have the least possible impact. This study concludes that more research is needed to help renew the NBR 8160 standard with support for changes in sizing conditions and installation / execution options.
